SAMUEL N. HURT, O'F TOLEDO, OHIO, ASSIGNOR TO TOLEDO SCALE COMPANY, OF TOLEDO, OHIO, A CORPORATION OIE NEW JERSEY.

INDICATOR.

Application filed August 28, 1926.

This invention relates to weighing scales, and particularly to indicators therefor, and its principal objectis the provision of an indicator hand adapted to co-operate with a weighing and computing chart and so constructed that weights and computed values on the chart may be read without errors of parallax.

Another object is the provision of an indicator hand of light but rigid construction.

Another object is the provision of an indicator hand having a reading and sighting line, with means for holding such reading and sighting lines taut.

Other objects and advantages will be apparent from the following description, in which reference. is had to the accompanying drawings illustrating a preferred embodiment ot my invention and wherein similar reierence numerals designate similar parts throughout the several views.

In the drawings Figure I is a front elevational view of a weighing scale equipped with an indicating chart and hand made according to my invention;

Figure Il is an enlarged elevational view of the indicator hand of my invention removed from the scale, parts being broken out;

Figure HI is a View in perspective of the upper end of the hand shown in Figure Il;

Figure 1V is a similar View of its lower end; and

Figure V is a plan view oiE the tip of the hand.

Referring to the drawings in detail, the chart l of the scale is n'ovided with an arcuate slot 2.

rlhe indicator hand 3 is attached at its lower end means of screws (not shown) which pass through suitable openings 4 to the load-counterbalancing element (not shown) ci? the scale. rlhe body of the hand is substantially channel shaped and the hand at its tip is provided with a brightly colored disk 5 which swings in the slot 2 and is, therefore, visiblefrom bot-h sides of the chart. The disk 5 is ilush with the chart and is provided on each side with indicating lines 6 adapted to co-operate with suitably numbered graduations on the front and back of the chart to indicate the weight of the load on the platform. The indication of the weight is thus visible both to the operator serian no. 132,143.

of the scale and to his customer, and, since the lines 6 and the. weight graduations with which the lines 6 co-operate are in the same plane, the scale can be read by both operator and customer without errors or" parallax.

At the lower end of the hand Vis a bracket 7 to which is attached a tlexible line 8 which extends upwardly through openings in an embossed portion 9 of thc hand, thence over a spool l0, and thence downwardly, its other end being attached to the bracket '7 by means of a retractile coil spring ll. The spool lO need not be revoluble, as the iforce ot the spring ll is suilicient to draw the line over the stationary spool and keep its parallel portions in approximately the same condition of tautncss.

rThe embodiment of my invention herein shown and described is to be regarded as illustrative only, and it is to be understood l that the invention is susceptible to variation, modilication and change within the spirit and scope of the subjoined claims.

Having described my invention, I claim:

l. In a device of the class described, in combmation, an indicator hand body, said body being substantially channel shaped throughout the major portion ol its length, a flexible line, means for attaching one end olf said iexible line to the lower end of said indicator hand body, a rearwardly oltset tip at the upper end of said indicator hand body, means for holding' a hight ot said line adjacent said tip, and a spring :For connecting the other end of said line to the lower end of said hand and holding said line tant with the portions on each side of its bight parallel.

2. ln a device o'll ythe class described, in con'ibination, a chart, said chart having an arcuate opening therein, an indicator hand adapted to move over the face of said chart, a line, means for attaching one end of said line to the lower end of said indicator hand, a tip at the upper end ot said indicator hand adapted to swing in said arcuate slot, means `for holding a bight of said line adjacent said tip, and resilient means for attaching the other end ot said line to the lower end of said hand.

3. ln a device of the class described, in combination, an indicator hand body provided with a substantially circular portion, a flexible line, means for attaching one end of said flexible line to one end of said indicator hand body, an offset tip extending from the llO circular portion of said han d, means for holding the bight of said line adjacent said tip, and resilient means 'for connecting the other end of said line to said hand and holding said line taut with the portions on each side oit its bight parallel.

4. In a device of the class described, in cornbination, a chart, said chart having an arcaate slot therein, an indicator' hand adapted to swing over the face of said chart, said hand being formed with a substantially circular portion adapted to swing in said slot, a flexible line, and a spool secured to said hand adjacent said circular portion, said line being adapted to pass over said spool and having its ends secured to one end oi' the hand, the portions of said line on each side of the bight formed by the spool being in parallel relation.

5. In a device of the class described, in coinbination, a charthaving an arcuate slot, an indicator hand adapted to swing over the face of said chart, said hand being formed with a circular portion adapted to swing in the arcuate slot in the plane of said chart, a flexible line, means for securing one end oi said line to the indicator hand, means adjacent the circular portionof said hand for holding a bight of said line, and resilient means tor securing the other end of said line to the hand whereby the portions ot said line on each side of said bight are held taut and in parallel relation.
